Question

我是java编程的初学者，但我需要使用spring框架创建一个java程序。 gui已经完成，但是我很难将页面从主页面，修补程序列表重定向到子页面，登录。

我的项目结构

SRC
- 主
- 的java
  - 玉米
  - 包名
    - PATCHLIST - //所有java文件作为控制器
- web应用
  - / WEB-INF
    - /弹簧
    - appServlet
      - servlet的context.xml中
    - 的web.xml

web.xml文件

    <?xml version="1.0" encoding="UTF-8"?>

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </context-param>

    <!-- Creates the Spring Container shared by all Servlets and Filters -->
    <listener>
